Out of memory error on EP server due to Web Dynpro Application

Hi Frndz...

I did sample Graphics application for demo, initality it was very fine , but todays itz giving "Out of memory error on EP server "

In this applicatio i used Timed Trigger which calls a method for every 2 sec's intervel, and that called method will genrate a grapic images, for this graphic input i taken a Current sec's ,

Date dt = new Date();

int sec = dt.getSeconds();

wdComponentAPI.getMessageManager().reportSuccess("Change rate/2 Secconds..."+ sec);

* int size = wdContext.nodeGnode().size();*

* for(int i=size-1;i>0;i--){*

IPrivateGraphicDemoView.IGnodeElement categoryElement =wdContext.nodeGnode().getGnodeElementAt(i);

  • wdContext.nodeGnode().removeElement(categoryElement);*

  • }*

* IPrivateGraphicDemoView.IGnodeElement categoryElement ;*

* for (int i = 0; i < sec ; i++) {*

* categoryElement = wdContext.createGnodeElement();*

* categoryElement.setText("" + i);*

* categoryElement.setSeries1(i-2.3);*

* categoryElement.setSeries2(2.5 - i);*

* wdContext.nodeGnode().addElement(categoryElement);*

* }*

Let me know that if we use Timed trigger UI ele , does we need to close this UI elemnt , if this is the case than how ??

I did this application 6 days back itz working very fine n i gave a demo also, than y this error is coming now only.

I hope there was some mistake in my code especialy in the FOR (itz going t5o infinet loop)

If anybady have any suggestions plz share with me.

    • Hi

      i hear is the porblem,

      , you are getting second and putting into the loop this loop never gone end and another thing aslo creating node on every increment of the loop,

      for (int i = 0; i < sec ; i++) {*

      categoryElement = wdContext.createGnodeElement();*

      correct this loop
